Normally, the distance between the road guardrail posts is between 2 and 4 meters. Under normal circumstances, a road column with a distance of 4 meters is combined with a road guardrail baffle to form a road guardrail. In areas with a high incidence of accidents, road guardrail posts with a spacing of 2 meters are usually selected to ensure the applicability of road guardrail baffles.

The gap between the road column and the guardrail baffle is fastened and connected with large screws. Gaps in some sections of the road may be fixed with anti-theft screws to prevent man-made disassembly and damage.

The installation method and hole position of highway guardrail should be well designed from the customization of cold roll forming equipment. There are different installation methods applied to different highway sections, which should be emphatically considered when customizing cold roll forming equipment.

The anti-impact level of highway guardrail is divided into A, B ~ SS level (a total of five levels). The grade starting with S is a guardrail baffle with a thickness of 4.0 to 6.0mm, which is usually used for highway guardrails on high-risk sections such as coastal roads and winding roads.

The bending arc of the wave guardrail roll forming machine can improve the overall aesthetics of the guardrail baffle and the torsion strength of impact resistance. In the production process of highway guardrail cold bending machinery and equipment, the cold bending process of cold roll forming one after another is adopted to make the guardrail keep the most ductile shape in its curved arc shape, so as to ensure its application in highway guardrail facilities and reduce harmfulness caused by vehicle accidents to the highest extent.
